UIStackView Change Upon Device Orientation...

I have an App that uses a UIStackView to contain an image view and a text view. For now, the arrangement has the image view on top of the text view. However, I would like, in the event that the iPad is in landscape, for the image view to appear on the left of the stack view and the text view on

If it's any consolation, I couldn't update my Retina MBP 15 either initially. When the installer was about to restart "An error occurred. Please try again." i had to reboot and install the OS again holding down some command key sequence. Only after a 1 hour install and putting a fresh install

The only thing you have to do is to call a method and add it as subview in your code - (instancetype)initWithFrame:(CGRect)frame configuration:(WKWebViewConfiguration *)configuration NS_DESIGNATED_INITIALIZER; It's max 3 minutes of work. On Thu, Oct 1, 2015 at 3:00 AM, Alex Hall wrote: > > > O
